Rear differential need to be rebuilt

[House003]

Nice truck! Where did you get the cammo panels?

Thanks! It was on the truck when I bought it, but I have replaced some of it. I don't remember what website I got it from but there are a lot of them. It's just a camo 3M vinyl wrap.. It goes on really easy and it's pretty inexpensive! Probably $100-$200

i kinda really want a detroit trutrac carrier.... its a helical gear set that gives power to both wheels CONSTANTLY... even when you turn, it powers both wheels.
unlike a posi that unlocks for tight turns

Not true. The TrueTrac is a posi unit. You're right about it being a gear system vs a clutch type though. Sounds like you want a Detroit Locker.

EDIT - As a side note though, the only way you're ever going to get 100% locked rear wheels is to install a spool instead of a standard carrier. Even true lockers have the ability to unlock slightly when required. Side note to the side note, if you ever do install a spool you'll probably want to upgrade lots of other things on your truck to not be constantly breaking things around corners.
